I think Ron White said it best when he told the story about the parking lot attendant. He doesn't take the attendant's crap. Attendant threatens to call the police and asks his first and last name.

He says "It's **** you ... *-*-C-K capital-Y-O-U. **** YOU!"

Seems fitting. Gets the message across And These guys have as much authority as a parking lot attendant anyway.
